How to verify my blog via flippa.com

I want to sell my blog via flippa.com auctions. To verify my ownership i need to insert metatag ir upload txt file. However there is no posibillities to do it for my self. Can wordpress staff insert manually metatag for my site? Or how can i verify my blog in other ways? Metatag <meta name="verifyownership" content="f9ba0cb8e1aa736532a028295aa6a4ec" />

Since everyone shares the same Theme code and meta tags are part of the Theme - manually inserting the code in the theme would put your meta code on all of the blogs that use the same theme - sort of a mess I would think -
